He's mostly in control of it. I think he spends most of his time just being perceptive of his surroundings and a bit quicker on the uptake, but only relative to a normal person. So nothing fancy at ground state. In combat, he can choose to step it up a bit, so it's more combat applicable. But bullet time is out of his control, that's purely stress triggered. He's still working on that.
Well, that, and the rest of your sheet, I'm ready to say 'yes'. Just gotta wait for Jane to say the same, and I'll move your sheet along to the accepted post.
Oh, one other thing I wanted to ask. Would or should the characters know about eachother before the game? Since the island is so small and not that populated, I imagine it'd only make sense if some of the PC's knew about each other or had some relationship, especially if they come from the same town.
I'll let players work out those details amongst themselves. Eis has always been a fairly small place, relatively speaking; the settlements have always been measured in the hundreds. So it's very possible that if they have the same home town, they know at least a bit about each other. Once me and Jane figure out how best to set up teams (and once we make sure we've got everyone that wants to play), I'll also say that team-mates should at least know each others full names, but probably a bit more. They'll be sharing the same group dorm rooms, taking classes together, eating in the cafeteria most likely together... so there's lots of opportunity there for group members to get to know the other members quite well.
Edit: Dorm rooms are set up mostly the same as the ones shown in RWBY. As the topic of the bathroom never showed up in the story yet, though, I'll say that each room has two separated showers, toilets, sinks, etc. Faculty members, since they live alone, have one bathroom, but it's their own private one (they also get actual baths instead of just shower stalls. Perks of the job!).
